HINGE CONTRIVANCE.

Application filed October 7, 1915.

To all whom it may conccm:

Be it known that .1, MAX lVnnnn, a citizen of the United States.residing at 1201 Starkweather avenue, in the city of Cleveland and Stateof Ohio, have invented a new and useful Improvement in HingeContrivances, of which the following is a specification, the principleof the invention being herein eX- plained and the best mode in which Ihave contemplated applying that principle, so as to distinguish it fromother inventions.

This invention in hinge contrivances relates more particularly to thattype of structure commonly adapted to support a screen door which it isdesired normally to have closed with some positive assurance other thana spring control for the assumption of such position. As such myinvention in volves a pair of pivotconnections so arranged as to bringabout a gravitational return of the door-to its closed position.

I am aware that the broad idea of having a door become tilted upwardlyupon its pivots when the same is moved through an arc of ninety degreesis known to the art, and further that such result was accomplished byhaving the lower part of the door forced away from the casing when thedoor was swung into a plane at an angle to the latter.

Accordingly this invention in hinge contrivances especially features anumber of improving structural details in association with such old)rinci ale in tiltin' or 'ravithinges. My object, besides feasibility,simplicity, durability and economy of manufacture, has been to supplythe advantages of accentuation, reversibility, reinforced light ness anda slight locking action, all of which, in the way of attainment, are tobe herein after explained.

Vi ith the foregoing and other objects in view the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but itis to be understood that changes, variations and. modificationscan be resorted to which come within the scope of the claims hereuntoappended.

Adverting to the drawings:

Specification of Letters Patent.

Patented May 15, 1917-.

Serial No. 54,519.

Fig. 2 is an elevation on a line of vision at ninety degrees to that ofFig. 1 showing the door in its full open position.

Fig. 3 is an enlarged top plan of the upper of two pair of coactingmembers, the same being purposely reversed from that shown in Figs. 1and 2 in order to emphasize the feasibility of so doing.

Fig. 4 is an enlarged view of the parts shown in Fig. 8 seen at an angleof ninety degrees toward the inside and with the parts in theirseparated position.

Fig. 5 is an enlarged bottom plan of the lower pair of coacting memberslikewise reversed from that shown in Figs. 1 and Fig. 6 is an enlargedview of the parts shown in Fig. 5 seen at an angle of ninety degreestoward the inside and with the parts in their separated position nd alsoone such part wholly sectioned and the other sectioned in part.

A door casing 1 surmounted in a door 2 includes a side upright 3 havingan invmrdly disposed edge 4 in proximity to which a screen door 5 isshown fitted as si'ipported by a pair of hinge contrivances en'ibodyingmy invention in their operative relation to *ach other.

What 1 term the upper supporting member 6 as shown in 2 and involves adownwardly projected arm 8, the former being intended to be secured nearthe top of the upright 3 and the latter accordingly e:; tending a givendistance therefrom. An in tegral of stif ening webs 9 are also providedacross the junction of the opposite side edges of the arms 7 and 8. Thearm 7 is fastened with three openings 10 under which the necessaryfastening screws pass. The arm 8 is provided with a circular opening 11of given size as appears in Fig. 3 and outwardly with respect theretowith an upwardly connected arcuatc rib 12, the locking purpose of whichwill in due time be explained.

. T he other of the upper coacting members is Hat and designated withthe numeral 13 and as also appears in Figs. 3 and 1 it comprises alongone edge a pair of substantially transverse ears 14 which are intendedto abut that edge surface of the door 5 which is opposed to the edge 4:of the casing. The portion 13 is in fact intended to be fixed near thetop of the screen door by means of screws (not shown) passing through aseries of openings 15 therein. The spacing of the portion 13 from thetop of the door should be assumed as properly selected with reference tothe distance that the member 6 is spaced from the top of the casing 1.Extending a given distance from the part 13 is an integral tubular arm16 provided with a T shaped tubular extremity 17, the diameter of whichis purposely less than the diameter of the opening 11 whereby either endof the portion 17 may be loosely pivoted in such opening. A stiffeningbar 18 is fitted within the arm 16 and may or may not project a slightdistance into the portion 17. This bar is seen in Fig. 3. Then one ofthe ends of the portion 17 is inserted through the opening 11 it isobvious that the arm 16 may rest upon and when moved ride over the rib12 and furthermore, because of the termination of the ends of the latterat the points shown, may slip off the same to cause a slight lookingbeyond each of such ends when the door is in either one of its twoextreme positions. The other or lower supporting member 19 is with oneeX- ception of similar formation as the member 6 to comprise adownwardly projected arm 20 and a horizontally projected arm 21reinforced by corner webs 22. Likewise, the arm 20 is fashioned with aplurality of openings for the insertion of securing screws. It should beparticularly noted that the arm 21 of the lower supporting member islonger than the corresponding arm 8 of the upper of the two supportingmembers such that its pivoting opening 2 1 may be disposed outwardly agreater distance from the casing 3 than is the opening 11. An arcuaterib 25 similar in every respect to the arcuate rib 12 is fashioned onthe upper surface of the arm 21 outwardly adjacent to the opening 24.

A correspondingly flat shaped portion 26 of the coiiperating member ofthe lower hinge contrivance similarly has a pair of ears 27 and screwopenings 28. It also has integrally projected therefrom a tubular arm 29with a corresponding T shaped 1101- low end 30. A reinforcing rod 31 isseen fitted within the arm 29 which latter is moreover purposely longerthan the arm 16. It should be understood asFig. 5 discloses that eitherone of the ends of the portion 30 has a loose pivot fit in the opening24 and it is furthermore manifest that by reason of the greater lengthof the arms 21 and 29 a double accentuation is effected in the way ofupward tilting of the door upon its pivots when these two assume acommon direction of projection. The loosening of both pivots readilypermits such upward tilting thereabout without any likelihood ofoccasioning a binding effect. The avoidance of a binding efiect at thepivots is made the less likely by the thinness of the arms 8 and 21.

In operation the different distances that the supporting members 6 and19 arespaced from the edge 4 allows the door to assume a true fit withthe casing of the door when closed, whereas when the door is drawn openthe portion 26 which is attached to the lower part of the door is shovedoutwardly and this in turn so tilts the door upwardly as to insure itsgravitational return to closed position.

As a manufacturing incident, the stiffening rods 18 and 81 serve a veryimportant additional purpose of compelling a neater and stronger jointat the junctions of the arms 16 and 29 with the T shaped ends 17 and 30respectively, owing to a reduction in the width of the spacestherebetween. This ensues because the presence of the rods 18 and 31prevents a complete alinement of the opposed edges of the ends 17 and30. As a further direct consequence the middle portions of those edgeswhich are continuous become arched. each around its respective rod toproject a slight distance in the direction of the parts 13 and 26 andthus more nearly close the gap which the formation by means of dieswould otherwise cause to remain.

.I claim: 7
